The premise for children of different ages to study together is that there are no other negative emotions, because some children are willing to imitate the actions of older children. If older children have some bad actions, they will be imitated by children intentionally or unintentionally. This result is not the original intention and purpose of mixed-age education.

Of course, in the period of enlightenment education, mixed-age education is possible, because children need to imitate, and imitators are generally people they like or admire, and they are generally excellent people, at least they think so. Such mixed-age education is possible.

However, if you reach the fifth and sixth grade of primary school, the disadvantages of mixed-age education will appear, because children in this period are active and changeable, and have the ability to think independently, so they can judge which thing is more beneficial to them. Personally, I think I can mix age education in kindergarten or the first three grades of primary school, and then forget it!
